How to install KTMflash and Read Infineon TC1797 transmission

Technical Support

1. The switch board is designed to work with J2534, this device uses the Ktag cables so the user can refer to the Ktag wiring diagram.

2. Advise you use Open Port2.0 as the protocol conversion equipment and work with PC.

3. There are 3 types of Bosch Infineon ECU :
1) The Infineon ECU before TPROT8.
2) TPROT8-10
3) The Infineon ECU after TPROT10 which is what we call GPT encrypted.

4. The Infineon ECU before TPROT8 is not encrypted, you directly uses the BOOT point
grounding, then follow the Ktag user manual to wire the cable and read the data.

5.For TPROT8-10,the Bosch Company set the anti-debugging mode, reading EEPROM needs no password and reading Flash needs password.
Therefore, during the reading process, there is an extra CNF1, Boot outputs low level and CNF1 outputs high level. When reading, Boot needs to add one small resistor and ground it. CNF1 to connect one 470ohm-2K resistance, then connect 3.3V, it's very important, otherwise the ECU will be burnout.
2 tips on reading the data:
1) BOOT and CNF1 must be connected when reading data.
2) Only connect BOOT not CNF1 When reading the password, otherwise the password can't be read out. Also you can follow the Ktag wiring diagram because Ktag controls the CNF1 turn on and off, so it can't be disconnected. When reading the password, you turn the two switches to the automatic mode, and to the On mode when reading the data, when the software prompts, you choose " Manually" then follow the message to turn on or off.

6. For GPT encrypted ECU, the S1, S2 and Boot cable are needed to connected when reading password, and the S1, S2 don't need to be connected when reading data.
